Hello, Please help me with the below questions. Please do not use hand writing. Some times it is very hard to read.

1. Find the ratio of speeds of an electron and a negative hydrogen ion (one having an extra electron) accelerated through the same voltage, assuming non-relativistic final speeds. Take the mass of the hydrogen ion to be 1.67x10 - 27 kg.13. Show that units of V/m and N/C for electric field strength are indeed equivalent.24. A 0.500 cm diameter plastic sphere, used in a static electricity demonstration, has a uniformly distributed 40.0 pC charge on its surface. What is the potential near its surface? 46. What charge is stored in a 180 [JP capacitor when 120 V is applied to it? 9. In what region of space is the potential due to a uniformly charged sphere the same as that of a point charge? In what region does it differ from that of a point charge
